A NULL pointer dereference flaw was found in the UNIX protocol in net/unix/diag.c In unix_diag_get_exact in the Linux Kernel. The newly allocated skb does not have sk, leading to a NULL pointer. This flaw allows a local user to crash or potentially cause a denial of service.

The remote SUSE Linux SLES15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2024:3985-1 advisory.

    The SUSE Linux Enterprise 15 SP5 RT kernel was updated to receive various security bugfixes.

An update of the linux package has been released.

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has kernel packages installed that are affected by multiple vulnerabilities:

  - A flaw was found in the Linux kernel's driver for the ASIX AX88179_178A-based USB 2.0/3.0 Gigabit Ethernet     Devices. The vulnerability contains multiple out-of-bounds reads and possible out-of-bounds writes.
    (CVE-2022-2964)

  - A stack overflow flaw was found in the Linux kernel's SYSCTL subsystem in how a user changes certain     kernel parameters and variables. This flaw allows a local user to crash or potentially escalate their     privileges on the system. (CVE-2022-4378)

  - A speculative pointer dereference problem exists in the Linux Kernel on the do_prlimit() function. The     resource argument value is controlled and is used in pointer arithmetic for the 'rlim' variable and can be     used to leak the contents. We recommend upgrading past version 6.1.8 or commit     739790605705ddcf18f21782b9c99ad7d53a8c11 (CVE-2023-0458)

  - A use-after-free flaw was found in qdisc_graft in net/sched/sch_api.c in the Linux Kernel due to a race     problem. This flaw leads to a denial of service issue. If patch ebda44da44f6 (net: sched: fix race     condition in qdisc_graft()) not applied yet, then kernel could be affected. (CVE-2023-0590)

  - A use-after-free vulnerability in the Linux Kernel traffic control index filter (tcindex) can be exploited     to achieve local privilege escalation. The tcindex_delete function which does not properly deactivate     filters in case of a perfect hashes while deleting the underlying structure which can later lead to double     freeing the structure. A local attacker user can use this vulnerability to elevate its privileges to root.
    We recommend upgrading past commit 8c710f75256bb3cf05ac7b1672c82b92c43f3d28. (CVE-2023-1829)

  - A use-after-free flaw was found in btsdio_remove in drivers\bluetooth\btsdio.c in the Linux Kernel. In     this flaw, a call to btsdio_remove with an unfinished job, may cause a race problem leading to a UAF on     hdev devices. (CVE-2023-1989)

  - A use-after-free vulnerability was found in iscsi_sw_tcp_session_create in drivers/scsi/iscsi_tcp.c in     SCSI sub-component in the Linux Kernel. In this flaw an attacker could leak kernel internal information.
    (CVE-2023-2162)

  - Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority because it was     the duplicate of CVE-2023-31436. (CVE-2023-2248)

  - A NULL pointer dereference flaw was found in the UNIX protocol in net/unix/diag.c In unix_diag_get_exact     in the Linux Kernel. The newly allocated skb does not have sk, leading to a NULL pointer. This flaw allows     a local user to crash or potentially cause a denial of service. (CVE-2023-28327)

  - A NULL pointer dereference flaw was found in the az6027 driver in drivers/media/usb/dev-usb/az6027.c in     the Linux Kernel. The message from user space is not checked properly before transferring into the device.
    This flaw allows a local user to crash the system or potentially cause a denial of service.
    (CVE-2023-28328)

  - qfq_change_class in net/sched/sch_qfq.c in the Linux kernel before 6.2.13 allows an out-of-bounds write     because lmax can exceed QFQ_MIN_LMAX. (CVE-2023-31436)

  - An issue was discovered in the Linux kernel before 6.1.11. In net/netrom/af_netrom.c, there is a use-     after-free because accept is also allowed for a successfully connected AF_NETROM socket. However, in order     for an attacker to exploit this, the system must have netrom routing configured or the attacker must have     the CAP_NET_ADMIN capability. (CVE-2023-32269)

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - When SMT is enabled, certain AMD processors may speculatively execute instructions using a target from the     sibling thread after an SMT mode switch potentially resulting in information disclosure. (CVE-2022-27672)

  - A flaw was found in the Linux kernel Traffic Control (TC) subsystem. Using a specific networking     configuration (redirecting egress packets to ingress using TC action 'mirred') a local unprivileged user     could trigger a CPU soft lockup (ABBA deadlock) when the transport protocol in use (TCP or SCTP) does a     retransmission, resulting in a denial of service condition. (CVE-2022-4269)

  - The current implementation of the prctl syscall does not issue an IBPB immediately during the syscall. The     ib_prctl_set function updates the Thread Information Flags (TIFs) for the task and updates the SPEC_CTRL     MSR on the function __speculation_ctrl_update, but the IBPB is only issued on the next schedule, when the     TIF bits are checked. This leaves the victim vulnerable to values already injected on the BTB, prior to     the prctl syscall. The patch that added the support for the conditional mitigation via prctl     (ib_prctl_set) dates back to the kernel 4.9.176. We recommend upgrading past commit     a664ec9158eeddd75121d39c9a0758016097fa96 (CVE-2023-0045)

  - There is a logic error in io_uring's implementation which can be used to trigger a use-after-free     vulnerability leading to privilege escalation. In the io_prep_async_work function the assumption that the     last io_grab_identity call cannot return false is not true, and in this case the function will use the     init_cred or the previous linked requests identity to do operations instead of using the current identity.
    This can lead to reference counting issues causing use-after-free. We recommend upgrading past version     5.10.161. (CVE-2023-0240)

  - There is a use-after-free vulnerability in the Linux Kernel which can be exploited to achieve local     privilege escalation. To reach the vulnerability kernel configuration flag CONFIG_TLS or     CONFIG_XFRM_ESPINTCP has to be configured, but the operation does not require any privilege. There is a     use-after-free bug of icsk_ulp_data of a struct inet_connection_sock. When CONFIG_TLS is enabled, user can     install a tls context (struct tls_context) on a connected tcp socket. The context is not cleared if this     socket is disconnected and reused as a listener. If a new socket is created from the listener, the context     is inherited and vulnerable. The setsockopt TCP_ULP operation does not require any privilege. We recommend     upgrading past commit 2c02d41d71f90a5168391b6a5f2954112ba2307c (CVE-2023-0461)

  - A flaw possibility of memory leak in the Linux kernel cpu_entry_area mapping of X86 CPU data to memory was     found in the way user can guess location of exception stack(s) or other important data. A local user could     use this flaw to get access to some important data with expected location in memory. (CVE-2023-0597)

  - A memory corruption flaw was found in the Linux kernel's human interface device (HID) subsystem in how a     user inserts a malicious USB device. This flaw allows a local user to crash or potentially escalate their     privileges on the system. (CVE-2023-1073)

  - A memory leak flaw was found in the Linux kernel's Stream Control Transmission Protocol. This issue may     occur when a user starts a malicious networking service and someone connects to this service. This could     allow a local user to starve resources, causing a denial of service. (CVE-2023-1074)

  - A flaw was found in the Linux Kernel. The tls_is_tx_ready() incorrectly checks for list emptiness,     potentially accessing a type confused entry to the list_head, leaking the last byte of the confused field     that overlaps with rec->tx_ready. (CVE-2023-1075)

  - A flaw was found in the Linux Kernel. The tun/tap sockets have their socket UID hardcoded to 0 due to a     type confusion in their initialization function. While it will be often correct, as tuntap devices require     CAP_NET_ADMIN, it may not always be the case, e.g., a non-root user only having that capability. This     would make tun/tap sockets being incorrectly treated in filtering/routing decisions, possibly bypassing     network filters. (CVE-2023-1076)

  - In nf_tables_updtable, if nf_tables_table_enable returns an error, nft_trans_destroy is called to free the     transaction object. nft_trans_destroy() calls list_del(), but the transaction was never placed on a list
    -- the list head is all zeroes, this results in a NULL pointer dereference. (CVE-2023-1095)

  - A flaw use after free in the Linux kernel integrated infrared receiver/transceiver driver was found in the     way user detaching rc device. A local user could use this flaw to crash the system or potentially escalate     their privileges on the system. (CVE-2023-1118)

  - A data race flaw was found in the Linux kernel, between where con is allocated and con->sock is set. This     issue leads to a NULL pointer dereference when accessing con->sock->sk in net/tipc/topsrv.c in the tipc     protocol in the Linux kernel. (CVE-2023-1382)

  - Due to a vulnerability in the io_uring subsystem, it is possible to leak kernel memory information to the     user process. timens_install calls current_is_single_threaded to determine if the current process is     single-threaded, but this call does not consider io_uring's io_worker threads, thus it is possible to     insert a time namespace's vvar page to process's memory space via a page fault. When this time namespace     is destroyed, the vvar page is also freed, but not removed from the process' memory, and a next page     allocated by the kernel will be still available from the user-space process and can leak memory contents     via this (read-only) use-after-free vulnerability. We recommend upgrading past version 5.10.161 or commit     788d0824269bef539fe31a785b1517882eafed93     https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/io_uring (CVE-2023-23586)

  - A NULL pointer dereference flaw was found in the UNIX protocol in net/unix/diag.c In unix_diag_get_exact     in the Linux Kernel. The newly allocated skb does not have sk, leading to a NULL pointer. This flaw allows     a local user to crash or potentially cause a denial of service. (CVE-2023-28327)

  - A NULL pointer dereference flaw was found in the az6027 driver in drivers/media/usb/dev-usb/az6027.c in     the Linux Kernel. The message from user space is not checked properly before transferring into the device.
    This flaw allows a local user to crash the system or potentially cause a denial of service.

  - A NULL pointer dereference flaw was found in the az6027 driver in drivers/media/usb/dev-usb/az6027.c in     the Linux Kernel. The message from user space is not checked properly before transferring into the device.
    This flaw allows a local user to crash the system or potentially cause a denial of service.
    (CVE-2023-28328)

  - hci_conn_cleanup in net/bluetooth/hci_conn.c in the Linux kernel through 6.2.9 has a use-after-free     (observed in hci_conn_hash_flush) because of calls to hci_dev_put and hci_conn_put. There is a double free     that may lead to privilege escalation. (CVE-2023-28464)

  - do_tls_getsockopt in net/tls/tls_main.c in the Linux kernel through 6.2.6 lacks a lock_sock call, leading     to a race condition (with a resultant use-after-free or NULL pointer dereference). (CVE-2023-28466)

  - An issue was discovered in the Linux kernel before 5.13.3. lib/seq_buf.c has a seq_buf_putmem_hex buffer     overflow. (CVE-2023-28772)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote SUSE Linux SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:1802-1 advisory.

  - Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized     disclosure of information to an attacker with local user access via a side-channel analysis.
    (CVE-2017-5753)

  - A double-free flaw was found in the Linux kernel's TUN/TAP device driver functionality in how a user     registers the device when the register_netdevice function fails (NETDEV_REGISTER notifier). This flaw     allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-4744)

  - A NULL pointer dereference flaw was found in rawv6_push_pending_frames in net/ipv6/raw.c in the network     subcomponent in the Linux kernel. This flaw causes the system to crash. (CVE-2023-0394)

  - Use After Free vulnerability in Linux kernel traffic control index filter (tcindex) allows Privilege     Escalation. The imperfect hash area can be updated while packets are traversing, which will cause a use-     after-free when 'tcf_exts_exec()' is called with the destroyed tcf_ext. A local attacker user can use this     vulnerability to elevate its privileges to root. This issue affects Linux Kernel: from 4.14 before git     commit ee059170b1f7e94e55fa6cadee544e176a6e59c2. (CVE-2023-1281)

  - A flaw was found in KVM. When calling the KVM_GET_DEBUGREGS ioctl, on 32-bit systems, there might be some     uninitialized portions of the kvm_debugregs structure that could be copied to userspace, causing an     information leak. (CVE-2023-1513)

  - A race problem was found in fs/proc/task_mmu.c in the memory management sub-component in the Linux kernel.
    This issue may allow a local attacker with user privilege to cause a denial of service. (CVE-2023-1582)

  - A flaw that boot CPU could be vulnerable for the speculative execution behavior kind of attacks in the     Linux kernel X86 CPU Power management options functionality was found in the way user resuming CPU from     suspend-to-RAM. A local user could use this flaw to potentially get unauthorized access to some memory of     the CPU similar to the speculative execution behavior kind of attacks. (CVE-2023-1637)

  - A use-after-free flaw was found in nfsd4_ssc_setup_dul in fs/nfsd/nfs4proc.c in the NFS filesystem in the     Linux Kernel. This issue could allow a local attacker to crash the system or it may lead to a kernel     information leak problem. (CVE-2023-1652)

  - A NULL pointer dereference flaw was found in the UNIX protocol in net/unix/diag.c In unix_diag_get_exact     in the Linux Kernel. The newly allocated skb does not have sk, leading to a NULL pointer. This flaw allows     a local user to crash or potentially cause a denial of service. (CVE-2023-28327)

  - hci_conn_cleanup in net/bluetooth/hci_conn.c in the Linux kernel through 6.2.9 has a use-after-free     (observed in hci_conn_hash_flush) because of calls to hci_dev_put and hci_conn_put. There is a double free     that may lead to privilege escalation. (CVE-2023-28464)

  - do_tls_getsockopt in net/tls/tls_main.c in the Linux kernel through 6.2.6 lacks a lock_sock call, leading     to a race condition (with a resultant use-after-free or NULL pointer dereference). (CVE-2023-28466)
